  As shown in FIG. 1, the exterior box 10 according to the present embodiment includes a rectangular parallelepiped composed of a top surface 11, a bottom surface 12, and four side surfaces 13 a to 13 d, and one of the four side surfaces 13 a to 13 d is opened and closed. It is configured freely. Each of the top surface 11, the bottom surface 12, and the four side surfaces 13 a to 13 d is configured by adhering heat insulating materials 21, 22, 23 a to 23 d on the inner side of the aluminum vapor deposition sheet, whereby the outer box 10 is insulated. It is composed of materials.

  The side surface 13a configured to be openable and closable is openable and closable with the side connected to the bottom surface 12 as an axis, and the other ends of the support strings 16a and 16b each having one end fixed to the side surfaces 13b and 13c are fixed. Thus, it can be opened only to a state parallel to the bottom surface 12. Further, a handle 15 made of a string or the like is attached to a region along the side opposite to the side connected to the bottom surface 12, and the side surface 13a can be opened by grasping the handle 15. Yes. Further, when the side surface 13a is closed, the side surface 13a is in a state of being fitted between the top surface 11 and the side surfaces 13b and 13c, but the length in the direction perpendicular to the connecting side with the bottom surface 12 is the same as that of the side surfaces 13b to 13d. By being slightly shorter than the length in the direction, a gap 17 is formed between the upper end side of the side surface 13 a and the top surface 11.

  The interior case 30 in this embodiment can be accommodated in the exterior box 10 shown in FIG. 1, and as shown in FIG. 2, side walls 32 a to 32 d are respectively provided on the four end sides of the bottom surface 31 made of a rectangle. It is configured to stand up and open upward. The bottom surface 31 has a shape slightly smaller than the bottom surface of the housing area surrounded by the top surface 11, the bottom surface 12, and the side surfaces 13 a to 13 d of the exterior box 10. The height of the three side walls 32b to 32d out of the four side walls 32a to 32d is slightly lower than the height of the housing area of the outer box 10 surrounded by the top surface 11, the bottom surface 12, and the side surfaces 13a to 13d. The height of the side wall 32a is about 1/5 of the height of the side walls 32b to 32d.

  The side wall 32a is provided with two handles 42a made of through holes, and a temperature display 34 for displaying the temperature in the interior case 30 is attached between the two handles 42a. The temperature display unit 34 displays the temperature in the interior case 30 measured by a temperature sensor (not shown) attached in the interior case 30.

  Each of the side walls 32b to 32d is provided with handles 42b to 42d made of through holes in a region along the upper end side, and an accommodation pocket 35 serving as a cold insulation accommodating portion is attached to an inner surface. The accommodation pockets 35 are made of, for example, a flexible polyester sheet, and are attached to each of the side walls 32b to 32d.

  A heat insulating sheet 33 is fixed to the side wall 32d on the upper end side of the handle 42d. The heat insulating sheet 33 is made of a material having heat insulating properties such as aluminum, and its width is equal to the width of the side wall 32d, and its length is equal to the sum of the width and height of the side walls 13b and 13c. ing.

  Below, the usage method of the cool box which consists of the exterior box 10 and the interior case 30 comprised as mentioned above is demonstrated.

  First, a method for housing the object to be cooled in the interior case 30 shown in FIG. 2 will be described.

  FIG. 3 is an external perspective view for explaining a method for housing the object to be cooled in the interior case 30 shown in FIG.

  When the object to be cooled is accommodated in the cold box composed of the outer box 10 and the inner case 30 configured as described above, first, the object to be cooled is accommodated in the inner case 30.

  In the interior case 30 shown in FIG. 2, the area surrounded by the bottom surface 31 and the side walls 32 a to 32 d is an accommodation area in which the object to be cooled is accommodated, and the upper part is opened. In this way, the heat insulating sheet 33 is rolled up, and the article 50 to be cooled is accommodated in the area surrounded by the bottom surface 31 and the side walls 32a to 32d from above. One end of the heat insulating sheet 33 is fixed to the side wall 32d and can be rolled up.

  After the article 50 is accommodated in the region surrounded by the bottom surface 31 and the side walls 32a to 32d, the heat insulating sheet 33 is placed on the article 50 as shown in FIG. As described above, the heat insulating sheet 33 has a width equal to the width of the side wall 32d and a length equal to the sum of the width and height of the side walls 13b and 13c. All articles 50 accommodated in the region surrounded by the side walls 32a to 32d can be covered.

  In this way, the article 50 that is to be cooled is accommodated in the interior case 30 shown in FIG. In addition, before the article 50 is accommodated in the interior case 30 or after the article 50 is accommodated in the interior case 30 and before the article 50 is covered with the heat insulating sheet 33, the accommodation pocket 35 is kept at a desired temperature. By storing the agent, when the inner case 30 is subsequently stored in the outer box 10, the article 50 is kept at a desired temperature regardless of whether or not the cold insulator is attached to the inner surface of the outer box 10. Can be kept cool. Moreover, compared with the case where the cold insulating agent is attached to the inner surface of the exterior box 10, the cold insulating agent is disposed near the article 50, and the cold insulating effect of the cold insulating agent can be improved.

  Next, a description will be given of a method for housing the interior case 30 in which the article 50 to be cooled is accommodated in the exterior box 10 as described above.

  FIG. 4 is an external perspective view for explaining a method of housing the interior case 30 in which the article 50 to be cooled is accommodated in the exterior box 10.

  When the interior case 30 in which the article 50 to be cooled is accommodated in the exterior box 10, first, the side surface 13 a of the exterior box 10 is opened. At this time, since the handle 15 made of a string or the like is attached to the side surface 13a, the side surface 13a can be opened by grasping the handle 15. Here, when another storage box or the like is placed on the outer box 10, the top surface 11 of the outer box 10 may bend and the side surface 13a may be difficult to open, but as described above. Since the gap 17 is formed between the upper end side of the side surface 13a and the top surface 11, even when the top surface 11 of the outer box 10 is slightly bent, it is avoided that the side surface 13a is difficult to open. . Note that when no other storage box or the like is placed on the exterior box 10, there is no need to create a gap 17 between the upper end side of the side surface 13a and the top surface 11 as described above. The length in the direction orthogonal to the side connected to the bottom surface 12 of the slab may be equal to the length of the side surfaces 13b to 13d in the same direction.

  And as shown in FIG. 4, the interior case 30 is accommodated in the exterior box 10 so that the side wall 32a may be on the near side from the surface on which the side surface 13a is opened.

  Thereafter, by closing the side surface 13a, the interior case 30 in which the article 50 to be cooled is accommodated is accommodated in the exterior box 10. Thus, the exterior box 10 is configured to accommodate the interior case 30. At this time, as described above, the bottom surface 31 of the interior case 30 has a shape that is slightly smaller than the bottom surface of the housing area surrounded by the top surface 11, the bottom surface 12, and the side surfaces 13a to 13d of the exterior box 10, Further, since the side walls 32 a to 32 d of the interior case 30 are provided upright on the four end sides of the bottom surface 31, the interior case 30 is accommodated in the exterior box 10. The 30 side walls 32 a to 32 d are in a state of being close to the side surfaces 13 a to 13 d of the exterior box 10. In addition, the height of the three side walls 32b to 32d of the interior case 30 is slightly lower than the height of the accommodation area of the exterior box 10 surrounded by the top surface 11, the bottom surface 12, and the side surfaces 13a to 13d. Thus, in a state where the interior case 30 is accommodated in the exterior box 10, the upper end sides of the side walls 32 b to 32 d of the interior case 30 are close to the top surface 11 of the exterior box 10.

  Thus, the state in which the interior case 30 in which the article 50 to be cooled is accommodated is accommodated in the exterior box 10, that is, the state in which the article 50 is accommodated in the cold box composed of the interior case 30 and the exterior box 10. In this case, the article 50 is transported or stored while being kept cold. When the interior case 30 in which the article 50 is accommodated is accommodated in the exterior box 10, the article 50 is surrounded by the interior case 30, the heat insulating sheet 33, and the exterior box 10. Is less susceptible to the temperature of the outside air.

  Next, a method for taking out the article 50 accommodated in the cold box as described above will be described.

  FIG. 5 is an external perspective view for explaining an example of a method for taking out the article 50 accommodated in the cold box made up of the interior case 30 and the exterior box 10.

  As described above, when taking out the article 50 accommodated in the cold box composed of the interior case 30 and the exterior box 10, first, the side surface 13 a of the exterior box 10 is opened. At this time, since the handle 15 made of a string or the like is attached to the side surface 13a, the side surface 13a can be opened by grasping the handle 15. In addition, when another storage box or the like is placed on the outer box 10, the top surface 11 of the outer box 10 may bend and the side surface 13 a may be difficult to open. Since the gap 17 is generated between the upper end side of the side surface 13a and the top surface 11, it is avoided that the side surface 13a is difficult to open even when the top surface 11 of the outer packaging box 10 is slightly bent.

  Next, as shown in FIG. 5A, the handle 42 a is grasped and the inner case 30 is pulled out from the outer box 10. That is, the side wall 32a of the interior case 30 becomes a drawer side when the interior case 30 is pulled out from the state accommodated in the exterior box 10, and the interior case 30 is accommodated in the exterior box 10 so that it can be pulled out. Will be. Moreover, in the interior case 30, since the height of the side wall 32a is lower than the other side walls 32b to 32d, the interior case can be obtained by using the side wall 32a instead of the handle by utilizing this difference in height. 30 is easily pulled out of the outer box 10.

  When the inner case 30 is pulled out from the outer box 10, the side surface 13 a can be opened only to the state parallel to the bottom surface 12 by the support strings 16 a and 16 b, so that the outer case can be moved while the inner case 30 is slid forward. 10 and can be placed on the side surface 13a as it is. If the size of the side surface 13 a is larger than the bottom surface 31 of the interior case 30, the side surface 13 a can be used as a work table when performing an operation of taking out the article 50 from the interior case 30 thereafter. Thus, the exterior box 10 has a configuration in which the interior case 30 accommodated in the exterior box 10 can be pulled out.

  Since the upper part of the interior case 30 is opened after the interior case 30 is pulled out from the exterior box 10, it is accommodated in the interior case 30 by rolling up the heat insulating sheet 33 as shown in FIG. The article 50 can be taken out. At this time, since the upper side of the interior case 30 is open, the interior case 30 is pulled out from the exterior box 10 as described above, so that the article 50 housed in the back of the interior case 30 is obtained. Can be easily removed.

  In addition, the interior case 30 is pulled out of the exterior box 10 by covering the article 50 with the heat insulating sheet 33 in a state in which the storage pocket 35 provided in the interior case 30 accommodates the cold-reserving agent kept at a desired temperature. Even in this state, the article 50 can be kept at a desired temperature.

  FIG. 6 is an external perspective view for explaining another example of a method for taking out the article 50 accommodated in the cold box made up of the interior case 30 and the exterior box 10.

  In the cold box configured as described above, when the interior case 30 is pulled out from the exterior box 10 and sufficient space for taking out the article 5 from the interior case 30 in that state cannot be secured, as shown in FIG. In addition, the heat insulating sheet 33 is rolled up in a state where the interior case 30 is accommodated in the exterior box 10. Then, while the upper side of the interior case 30 is opened, the height of the side wall 32a on the drawer side when it is pulled out from the state accommodated in the exterior box 10 is 1 / of the height of the other side walls 32b to 32d. Since it is about 5, the article 50 accommodated in the interior case 30 can be taken out from the side wall 32a side. In addition, although the height of the side wall 32a should just be lower than the height of the side walls 32b-32d, in order to take out the article | item 50 from the side wall 32a side in the state in which the interior case 30 was accommodated in the exterior box 10, It is preferable that it is 1/2 or less of the side walls 32b to 32d.

  In this embodiment, the storage pocket 35 is attached to the inner surfaces of the side walls 32b to 32d, but the storage pocket 35 is attached to the outer surfaces of the side walls 32b to 32d. Also good. In that case, since the side walls 32b to 32d are interposed between the article 50 housed in the interior case 30 and the cold-retaining agent, the article 50 may be excessively cooled or condensation may occur on the article 50. Can be avoided. The storage pocket 35 is not limited to the side walls 32b to 32d, and may be attached to the side wall 32a or the bottom surface 31 by appropriately setting the size.

FIG. 7 is an external perspective view showing another embodiment of the outer box constituting the cold box of the present invention, and shows a state in which the side surface 13a configured to be openable and closable is opened.

  As shown in FIG. 7, among the side surfaces 13 a to 13 d of the outer box 110, the side pocket 13 a that can be opened and closed is provided as a storage pocket 135 for storing the same cold insulation agent as that attached to the interior case 30 shown in FIG. 2. You may attach to the surface inside the other side surfaces 13b-13d.

  When the exterior box 110 configured as described above is used, when the cold insulator is not attached to the inner surface of the interior case 30, the exterior case 110 is accommodated in the interior case when the interior case is accommodated in the exterior box 110. Since the interior case is interposed between the object to be cooled and the coolant, it is possible to avoid that the object to be cooled is too cold and that condensation is generated on the object to be cooled. That is, the interior case is useful for avoiding that the object to be cooled is too cold or that condensation occurs on the object to be cooled.

  FIG. 8 is a view showing another embodiment of the outer box constituting the cold insulation box of the present invention.
